I am also running W3 Total Cache. My settings in Striking>Advanced are:

Combine Js: OffCombine CSS: OffMove Js to bottom: On

If I switch on Combine CSS/Js, my site breaks.

On W3 Total Cache I keep Minify CSS On but I must keep Minify Js Off, as it prevents my slideshow from working. I am really looking forward to finding the way to minify Js as it is the only thing that is stopping my site from having a score of 97 instead of 87 running Google Page Speed Test.
